“…We have adopted the precision shadowmask method of color pixelation to produce individual R,G,B emitters, similar to the work of Fukuda et al [5]. In this section we will discuss the choice of available shadowmask technologies, the precision requirements on the shadowmasking subsystem, and the potential for scaling up this technology for manufacturing.…”

In October 1999, Eastman Kodak and Sanyo Electric jointly announced the development of a high quality, 2.4 inch diagonal Full Color active matrix Organic Light Emitting Diode (OLED) display. This technology demonstration resulted from the successful integration of Kodak's organic electroluminescence display technology and Sanyo's low temperature polysilicon TFT technology. Commercial samples are expected to reach the market in 2001. The active matrix OLED displays feature a wider viewing angle and a faster response speed than conventional LCDs. With its low power consumption, high brightness and thin design, these OLED displays when incorporated in digital cameras, personal digital assistants (PDA), videophones and other portable imaging devices, will offer a superior value proposition to consumer electronics products. Several OLED display designs are under development now to serve various market segments. This paper will summarize the status of active matrix full color OLED display development, the key technical challenges, and the path ahead.

A new series of blue emitting dopants based on pyrazine derivative has been synthesized and used in electroluminescent (EL) devices. The EL cells have a configuration of ITO/NPB/TPBI doped with pyrazine derivatives/Mg : Ag; where NPB is N,N 0 -bis-(1-naphthyl)-N,N 0 -diphenyl-1,1 0 biphenyl-4-4 0 -diamine and TPBI is a trimer of N-arylbenzimidazoles. Four different pyrazine derivatives have been used and their photoluminescence and EL properties were compared in the light of their molecular structures. EL devices giving bright blue emission peaked at 468 nm; an optimum luminance of 1200 cd/m 2 at a current density of 150 mA/cm 2 ; and a current efficiency of 1.4 cd/A at 5 mA/cm 2 have been obtained.

“…Monochrome 2 and multi color OEL displays 3,4 are now available in commercial form. In addition, a number of full-color OEL displays based on small molecular weight vacuum-deposited thin films have been developed through the use of patterned lateral RGB emitters [5][6][7][8] . So the expectation of the full-color OEL displays is getting bigger.…”

Full-color displays of passive-matrix driven organic electroluminescence panels

2.2 inch diagonal full-color passive-matrix displays of organic electroluminescence panels were fabricated, and the possibility of mass production was examined. The panel consisted of 132 x 162 pixels, and each pixel had three subpixels of red, green and blue emission in line. The panel contained stripe-shaped ITO lines, multi layers of organic materials, and cathode lines orthogonal to ITO lines. The organic layers of the electroluminescence panels were fabricated by vacuum evaporation method. Full-color emission was performed by patterning directly the emitting layers of red, green and blue color through metal mask in order to take most advantage of the luminous efficiency of electroluminescence. Pixel size of 0.272 mm x 0.264 mm was performed by vacuum evaporation using metal mask. This simple-structured panel was driven with passive matrix drive method. Dual scan drive method was adopted to lower the duty ratio, which made the peak luminance lower. Total thickness of the module was only 2.5 mm. We started pilot production of the 2.2 inch diagonal full-color organic electroluminescence panels, and good manufacturability is promised.
